LANTERN.

SPECIFICATION forming part of Letters Patent No. 355,240, dated December28, 1886.

Application filed June 15, 1886. Serial No. 205,225.

A\VOOD, a citizen of the United States, residing at Omaha, in the countyof Douglas and State of Nebraska, have invented certain new and usefulImprovements in Lanterns; and I hereby declare the following to beafull, clear, and exact description of the same.

My present invention relates to the form of lantern for which LettersPatent of the United States, No. 316,425, were granted. to me on the21st day of April, 1885. 1

The construction I desire to cover in the present applicationisidentical with that'shown and described in my said Letters Patent, eX-cept as to the heat-chambers in the. tubes, which I now omit, since thedevice without them operates more satisfactorily, and affords, as I havediscovered by experiment since applying for my aforesaid Letters Patent,a decided improvement upon the device shown and described therein, owingto the tendency of the chambers to accumulate gas and produce explosion,which not only destroys the lantern, but is liable to entail disastrousconsequences.

In the accompanying drawings, Figure l is a sectional elevation of myimproved lantern; Fig. 2, a side elevation of a portion of the same,showing details; Fig. 3, a sectional plan View taken on the line 3 3 ofFig. 1; and Fig. 4 a plan view of the burner and oil cup or reservoir ofthe lantern.

The frame A, globe B, ventilating or draft top 0, and oil cup orreservoir D, with the base D, may be of the'usual or of any improvedconstruction.

'ner to cause the lower bent portions to lie within the oil-cup andextend nearly to the bottom of the same, thus presenting a comparativelylarge surface for contact with the (No model.)

oil. The shorter arms, 6', of the tubes E project a short distancebeyond the upper surface of the top d, through the latter in line withthe wick-tubes f and on opposite sides of the same, and are providedwith short pipes or tubes 1), bent, as shown, toward their upperextremities and provided with flaring months a, to extend above thewick-tubes. The longer arms, 6, extend vertically through the globe B toor into the draft-top O, and thereby serve as chimneys to create thedraft necessary to draw the heat from the flame at the wick-tubesthrough the tubes 12 down and up through the tubes E, and thereby heatthe contents of the oil-cup.

The tubes 1) are not rigid in their positions upon the projecting endsof the shorter arms, 0, of the tubes E, but are adjusted in any suitablemanner (by simply seating them as shown, if desired) to permit theflaring months 0 to be turned toward and from the flame, and thus 7permit the temperature of the oil to be regulated by controlling thedegree of heat introduced through the oil-cup.

The heating of the oil renders its combustion perfect to an extent thattends to prevent smoke, and thus the globe B is kept clear.

I am aware of a lamp provided with a bent tube, the bent portion beingwithin the oilchamber and the short arm of the tube having a bellmouthextending over the wick-tube. I i
